i have a friend who runs the 10 w7 w/the 500/1. sounds like a pair of 12's easy. very nice setup. too many variables in components. you'd have to narrow down your preferences (cost, 2-way or 3-way..etc)
Of all the setups i have done the JLW7 and the 500/1 in the H.O. wedge box....i have never seen a unhappy costomer....they all come back and say damn i can't believe it's a single 10!!
i have 2 jl 10w7s on 2 jl 500/1s in slot ported enclosures, and i must say myself im pretty astonished at the output of these subs... 1 is enuff, but being i had them sealed before, i had 2... well porting them definately made a huge difference. also, im running the jl XR 650csi components on a jl 300/4 amp. i like em, they are clear, but i blew one of my tweeters when i improperly hooked it up to the x-over (my fault). but yea if u got the room, lik every1 else has said, ive heard the HO box is sweet, i just aint got no money left over for 2 of them lol
definatly get the high output.. JL has patented their design and provides alot more output than a normal slot ported box.. upgrade the component set if u want, but thats ur call.
